[ 1 ] - Proposed ST-Slotted-CS-ALOHA Protocol for Time Saving and Collision Avoidance
Time Saving and energy consumption has become a vital issue that attracts the attention of researchers in Underwater Wireless Sensor Networks (UWSNs) fields. According to that, there is a strong need to improve MAC protocols performance in UWSNs, particularly enhancing the effectiveness of ALOHA Protocol. In this paper, a time-saving Aloha protocol with slotted carrier sense proposed which we c...
[ 2 ] - Improving LoRaWAN Performance Using Reservation ALOHA
LoRaWAN is one of the new and updated standards for IoT applications. However, the expected high density of peripheral devices for each gateway, and the absence of an operative synchronization mechanism between the gateway and peripherals, all of which challenges the networks scalability. In this paper, we propose to normalize the communication of LoRaWAN networks using a Reservation-ALOHA (R-A...
[ 3 ] - Comparative Study between Hologram Technology and Augmented Reality
The great development witnessed by our current age has led to the emergence of many diverse modern technologies, one of these advanced technologies is Hologram technology and Augmented reality technology, These two technologies are somewhat similar to somewhat, as it can be said that they perform almost the same purpose, and at the same time, Hologram technology differs from augmented reality i...
[ 4 ] - Using Machine Learning Algorithms for Automatic Cyber Bullying Detection in Arabic Social Media
